PACKAGE OF ELBOWS.

Application filed. March 25, 1915.

To all whom it may concern.

Be it known that I, ALBERT G. SGHERER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Packages of Elbows Suitable for Handling and Shipment, of which the following is a specification.

My present invention has relation to the packing of elbows formed of sheet metal, such as are employed in heating and ventilating, and like systems, in secure and convenient packages which are not liable to come apart during handling or shipment.

So far as I am aware the present methods of making packages of the elbows is to telescope a suflicient number thereof to form a continuous passage and to crate the elbows so assembled or to wire them together with a spirally wrapped wire. Crating is eXpensive, and is unnecessary except to hold the elbows together as the elbows are of a structure which gives them considerable strength. Even when the spirally disposed wire is tightly drawn, the separate coils thereof are liable to slip and permit the elbows to come apart. It has heretofore been considered impracticable to placea wire circumferentially instead of spirally around the entire package because of the extreme liability of slipping and becoming displaced.

I have made it possible to circumferentially and securely wire a package of elbows together for shipping by means of the structure illustrated in the accompanying drawing in which,-

Figure 1 is a view of a number of elbows telescoped to form a continuous passage and circumferentially wired. Fig. 2 is a view of a single elbow showing the means permitting the circumferential wiring of the package when such elbows are telescoped.

Similar reference characters refer to similar parts in the respective views.

I have illustrated my invention applied to a ninety degree elbow made of two end pieces 8 and 4, and two intermediate pieces, 5 and 6, respectively, but it will be obvious that my invention may be applied to other than ninety degree elbows of four pieces each. One end 3, of the elbow is preferably Copies of this patent may be obtained for Specification of Letters Patent.

crimped at 7 in the usual manner to render it easy of entrance into a section of pipe while the opposite end piece 4, is left nocrimped to receive the usual crimped end of a pipe.

Elbows are usually formed of sections as above described, each section being made of a properly laid out and cut blank rolled into cylindrical form and having their overlapping edges secured together by rivets 8, or in any suitable manner. In preferably, an overlapping portion of a section of an elbow I cut out a tang 9, which is adapted to be bent up at right angles to the adjacent portion of the section, and in this tang, 9, I provide a hole, 10, of a suitable size to receive the encircling tie-wire 11.

After the elbows have been telescoped one into another as above described, a tie-wire, 11, is passed through the holes, 10, in the respective tangs 9, and the ends of the tiewire are securely fastened together which secures the several elbows together in a strong and secure package capable of resisting the ordinary exigencies of handling and shipment.

What I claim is l. A package of elbows comprising a plurality of elbows assembled to form a continuous passage, tangs formed from the metal of the respective elbows, said tangs having holes therein, and a tie-wire circumferentially surrounding said package and engaging the holes in said tangs.

2. A package of elbows comprising a plurality of elbows assembled to form a con tinuous passage, tangs formed from the metal of the respective elbows, and a tiewire circumferentially surrounding said package and engaging said tangs.

3. An elbow adapted to be formed into a package comprising a hollow metallic shell having a tang extending therefrom and adapted to be bent laterally thereto.
